Abstract
Abstract. Native freshwater mussels have seen dramatic declines in western North America, but effective monitoring and management of these organisms can be difficult due to their cryptic nature. We used environmental DNA sampling—a sensitive, noninvasive genetic technique—to examine the contemporary distribution of 2 native freshwater mussel species, Anodonta nuttalliana and Margaritifera falcata, in Utah and western Wyoming. We sampled water bodies with historical presence, as well as additional water bodies and locations with promising habitat for the species. We detected A. nuttalliana from 39% of the 31 water bodies sampled and M. falcata from 16% of the 25 water bodies sampled. We demonstrated that environmental DNA technology is an efficient method for determining the distributions of freshwater mussels. Resumen.

摘要北美西部的本地淡水贻贝数量急剧下降,但由于它们的隐秘性,对这些生物的有效监测和管理可能很困难。我们使用环境DNA取样——一种敏感的、非侵入性的基因技术——来检测两种本地淡水贻贝物种——Anodonta nuttalliana和Margaritifera falcata——在犹他州和怀俄明州西部的当代分布。我们采样了历史上存在的水体,以及其他有希望为该物种提供栖息地的水体和地点。31个水体中有39%检出nuttalliana, 25个水体中有16%检出falcata。我们证明了环境DNA技术是确定淡水贻贝分布的有效方法。Resumen。Mejillones de aguagudulce native / visto reducciones dramáticas en el oeste north americano;在禁运期间,请登录difícil de detectar debido,并将其添加到críptico。美国环境保护协会(Usamos el ADN del ambiente),对无侵入性病毒的空气交换系统(ADN)和空气交换系统(ADN)进行了研究,对2种瓜蚜螨、肉芽蚜螨和镰蚜螨进行了研究,并对犹他州和怀俄明州的空气交换系统(oestes)进行了研究。墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥墨西哥在31个不同种类的瓜类中,nuttalliana检出率为39%;在25个不同种类的瓜类中,falcata检出率为16%。建立tecnología建立隐含的民主制度和建立环境的民主制度是为了有效地建立确定的经济分配机制,建立经济分配机制。
